TO WHOM IT MAY CONCERN:

Know all men that I, FRANKLIN NELSON, of Wyandotte, county ot' Wayne, and State of Michigan, have invented a new and useful Improvement in a Punching-Machine; and I do declare thatthe following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the lettersv of reference marked thereon, and being a part of this specification.

The-object of this invention is to obtain a machine of greAat power for punching or perforating metals.

Figure l is a perspective View oi' the apparatus complete, same letters of reference applying to same parts Y in the different views of the machine; and

Vlever F, and pass through and oscillate in proper openings connecting the levers F and Figures 2, 3, and i are sectional views of the operating parts of my machine. In this construction ot' n'iy apparatus, the levers D and E are placed in the frame A, the upper end of lever D being fastened in said frame by hinge-joint K, its lower end being connected to similar fasteningto Ythe lever F- and side-plates O. Thelever E is also secured to the lever F and side-plates O in the same manner; the two levers D and E operate upon the trunnions N. The lower end of the lever E is hinged to the punch-head J, which` is secured in its position by the guide C, through whichA it runs to the die-plate L; The lovers D and E, punchhead J, and lever F are kept in their proper places by the sliding blocks vI, which work in proper slots in the jaws et the trarne A, and covered by the cap-plate L. The trunnions or pins T are rigidly attached to said in the sliding blocks I, which, perhaps, may be termed a cross-hend, working in appropriate ways, as heretofore described.

The vibrating ends of the levers D and E are secured to tbe lever F by trunnions or pins N, oscillating in plate O, and all'the levers, D, E, and F, being supported or suspended from thehingejoint K. Gr are levers, H, as shown in the drawing, and making a very powerful combination of leverage. The slot B `is an opening in the trarne A, to admit of room to manipulate tho material lbeing operated upon.

Fig. 3 sho'ivs a side view ot' the levers in a contracted position, with'pnnch elevated. To force the punch through the material being operated upon, the levers D and E are thrown into a vertical posit-ion, (as shown by red lines,) perpendicular to each other, hy depressing the lever F.

My machine may be operated with or Without the additional levers Gr and H, by a rreadle attached to the long arm of the lever F, or by any other device or power that may he desirable.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The pendulum-levers D and E, working upon fulcro. K and P, operated by lever F, when secured to sliding blocks I hy the trunnions T, in combination with Athe plates O, trnnnions N, and operating substantially :is heroin sot forth.

Q. The combination of all the ahove-deserihed parts, when used in connection and any proper frame A and any suitable levers F, G, and H, arranged and operati the purposes herein described;

` FRANKLIN NELSON.
